' or sYnACUsE, new YORK, A CORPORATION or new YORK PRINTING MACHINE" i i This invention relates to ajprinting machine adapted to be used more particularly in public libraries for keeping records of the different borrowers of books and other g matter issued by the libraries as temporary loans and also for recording the dates of issue and return of such'books or other matter to and'from the borrower,but obvlously the machine may be used for many other v date'recordsmay be more expeditiously and effectively impressed upon the record cards than has heretofore been practiced.

In other, words I have sought to provide a conveniently portable machine whereby the identification records and date records maybe made on two separate cards in one and the same operation.

Another object is to provide means whereby the identification character and date of issue or return of theborrowed article may be simultaneously impressed upon thesame 7 record card in alineinent with each other. 36 'Another object is to provide means where-v by the record card or cards'may be advanced inthe machine, one line spaced at a time follo'vi 'ing each printing operation. M A. further object-is to provide an adjustable carrier for a .pluralityof removable dateprinting plates capable of being removed and replaced by different type plates and at th same time to permit thecarrier to be adjusted endvvise for bringing any one of hetype plates into alinement with the iden tification type plate so that any one of different dates of borrowing or return may be recorded upon a card opposite the identification impression. V j

Another object is to providea housing for the various 'movingparts with amovable lid or cover upon which certain parts of the printing mechanism, are mounted and to causes-aid lid or cover to be automatically Application filed September 23, 1 929. Serial No. 394,531.

A keeper plate 6 is mounted upon the inner face'of one of the end walls of the base section '1; to

form apart of a lid rocking mechanismhere-- inafter described.

' P la ten action pair of opposed-upright platen-jaws '.7-'"and 7 are journaled at'theirlower ends upona lengthwise bearing shaft .8'--v bottom and substantially midway between the front and rear walls thereof, shown more clearly in Figurez9. 7

i e The platen-j aws extend'upwardly from the shaft 8 to aplane just below thetop wall i' or lid- 2 and are provided near their up-- per ends with resilient platens -9+ of soft rubber or equivalent material seated in sockets inthe inner oradjacent sides iofthe jaws 1 equal distances from the aXisof the shaft 59'' '8 to cooperate with interposed typeplatesfor making impressionsof the type;

upon the: cards] v i i The inner face of each of the 'platens r9 is divided by .a transverse recess +10 to form's-separate platen sections 11: and

'l'1-", the platen sections 11 being upon the card when the platen-jaws, are; V

r 1 machine and'rextended beyond opposite ends adapted to cooperate with the dating type while the sections 11 are arranged to, cooperate with the identificati0n type for re producing the impressions of the type-plates closed. t o .7 l w i One ofthe platen-jaws as is made in the'form of a" bell-crank llever having a rearwardly projectingarm '1-2''carryi-ng at its the base section '1 is j provided with suitable feet lof rubber rear end a roller ''l3'-f for engagement with the underside of a cam 1.lwhich is secured to a transversely extending rock shaft +15%- and is adapted to engage a roller -16 on the rear side of the jaw 7" as shown more clearly in Figure 9.

. The roller -'16 is mounted on the jaw "7 between the pivotal bearing 8 and" corresponding plat-en +52% so that when th -oam shaft withthe earn 14' ithereon is rocked in the directionindicated by arrow X the aws will be forced to their. printing positions against the action of a; re-

tracting spring-17% which serves to automatic'ally open the jaws and incidentally to hold the rollers 13' and 16 in contact with opposite faces "with the cam 1 l Figure9. I

The cam shaft -l 5 isjournaled suit-u able bearings ,'18- on the base section l parallel awithv the shaft "8 and extends throughone of the end walls thereof, its outer. end being provided with a hand crank 19- by which it maybe rocked about its axis.

Printing mechanism preferably employ two type'carriers as 20 and 2l actively arranged side by side lengthwise of and betweentheplatenaws -7 and -.7.+ with their type in alinementfwith each other and with the 7 platen sections-41+- and "r'-ll.', the carrier 20.being provided with a plurality of, in this instance fountype plates,22

,r-for impressing upon one or moreicards the date of issue or date of return of the bor-V rowed article while the type carrier 2l is provided with a single type plate '23 for lmpressing uponthecard 'or cards the identification number or the borrower. V i 1 V 7 The type of both of the carriers are adapted to be simultaneously impressed'upon the card or cards in alinement with each other by the closing movementof the jaws ''7 and other character of 7 through the medium of an inking rib-l bon or equivalent transfer member presently described. "f i' 'Suitable'means is provided for guiding the type carriers 20 and '21f when inserted into the machine between'the normally spaced platen jaws 7f' and 7 said guiding means being preferably' mounted upon the +25- to move therewith as theflid is opened and closed. v f

For this latter purpose a pair'of guide bars -21 are mounted at their ends upon longitudinally spaced brackets %25+ just above the lid 2, said bars being arranged in parallel spaced relation lengthwise of the tween the jaws, the brackets ?25"L being secured to thelid by screws or other suitable receiving additional guide plates 27 which are arranged in transversely spaced relat1onw1th their upper ends secured in radial slots in the lower inner sides of the bars "-24l-- and their remaining portions extend ing'in'to'the interior of the base section 1- between the platen sections 11- and 1 11'.- vof the jaws -9 as shown more clearly in Figures 9, 10 and 11 to assist in V gulding the carriers and -;-2l and holdingfthe same inoperative position during the printing operation.

The guide opening between the bars 21 and also between the guide plates -27 is divided by a partition v28 into two sep arate passages 27 and 27 as shown more clearly in Figures 1 and 7, the leftha-nd passage being adapted to receive the type carrier 20-, Figure 10, while the righthand passage serves to receive the type carrier -2l, Figure 11. I

The lefthand passage 27 is open at the bottom to permit the passage of the lower end of the type carrier 20* therethrough but the passage 27" for the carrier -21- is preferably closed at the bottom to form astop 29- for engaging the lower end of thecarrier 21 and limiting the downward movement thereof, see F igure, 11.

This stop 29 is formed by uniting the lower edges of the guide plates 27 across the intervening passage 27". The upper end of the partition 2 8 is secured to T and between the guide rods 24l' and-ex-- tends downwardly therefrom to a point slightly above the stop 29 shown in Figure 7, and also assists in guiding the type plate ,20 in its vertical movement.

A similar partition or outer end guide 28" is secured at its upperend to the guide rods24 to extend downwardly therefrom between the guide plates *27 and together with the partition .28 assist in guiding f the carrier v-21 infits vertical movements inthe passage 27-. 7 Q 7.

The guide passage 2 for the type carrier 20 is of approximately the same width as the portion of the type carrier passtherethrough while the passage 27 for thetype carrier 21 is considerably wider-than the passage '27 and corresponds approximately to thewidth ofthe carrier ,21 which, in this instance, is of about the same width as the cards -a and '-'a to be printed for convenience-of manufacture of the cards andcarrier 2l.

The lid 2 is provided with additional guic le members 30,secured toand projecting upwardlyfroni the upper face of the lid in spaced relation to the lefthand end bracket 25 a distance corresponding approximately to the width of the cards a and -a to be printed, said guide members being located at the outer sides of and adjacent the guide rods 2 lto cooperate with the lefthand bracket 25, Figure 1, for guiding the cards a and a' in their vertical movements through the corresponding portion of the guide opening -26, said cards being inserted through the openings across the outer faces of the rods -24- as shown in Figures 10 and 11.

The type carrier 20 is preferably made of sheet metal and is provided with a length wise o enin 22 therethrou h ofwith P e g plate will beengaged with a stop shoulder 22, Figure 7 to cooperate with the upper wall ofthe opening -22- for holding the type plates against vertical displacement.

These type plates are preferably made of thin type meta-l having date type embossed thereon for making corresponding impressions upon the cards 'a and a when the latter are placed in position for printing and the jaws -7 and 7- are brought to their printing positions, said type plates being sufficiently resilient to permit the lower plate to be sprung out of engagement with the stop 22 when it is desired to remove the plates from the guides 31 by endwise displacement after which the removed plates may be replaced by other type plates bearing different dates.

In order that both cards a and a may be printed simultaneously each type plate -22- is provided with two'rows of similar type, one above the other and enibossed in opposite directions so that when the jaws 7- and -7 are brought to their printing positions corresponding impressions will be made upon outer faces of both cards.

The type plate 23 of the carrier 21 is made of thin type metal and secured in an opening in said carrier in a manner somewhat similar to that shown in my pending applieation,.Serial Nd 394,530, filed September 23, 1929, said plate 23 being provided with two rows of type arranged one above the other and embossed in opposite directions sso'asyto produce simultaneous impressions to their printing positions, these latter im presslons bein g I made "simultaneously with i those from the type plate -22f during :th

- same operation of theplaten jaws:

w I The type plate .23 is preferably secured to the lower lefthand corner of the carrier -21 a distance from the lower edge therelower end engaged with the. stop 29. the

type pl'ate will be in position between the inner faces of the platen sections flle and l1+ to permit the latterfto transfer the impressions of the type "plate onto both cards The type-carrier '20-' is adjustable its guide passagej.27 V to bring 1ts several type plates successively into a" posltion between the platen sections 10-l and m l-10 and thereby to permit. the impres-' sions of the type to be made upon both of the cards .aand a when the jaws 7 and +7 are closed it being under stood thateachadjustment of the carrier +'will bring one of the plates 22 into alinement with the plate --23:. of the carrier -21 wherebythe impressions of the alined plates will be made simultaneously upon both of the cards.

Suitable means is provided per end of the'carrier'is provided with a lateral ofiset 20 carrymg a pendant tooth rack i 82 which 1s: guided in a vertical opening.33 in a guide block' which 1s secured to the underside of the lid 2 asis shown more'clearly in Figures and 7 This tooth rack is engaged by a' gear ,--35' which is secured to arocl: shaft -36- the later being journ'aled insuitable hearings in the block +34 to extend through the end'wall thereof to the exterior of said shaft being provided withxa hand crank 37 by whichit may be rockedupon its aXis for effectingthe vertlcal movementof the carrier 20 through the mediunilof the rack 32- and gear .35.

In order that the positioning of the-type plates of the carrier -2O+ maybe accurately determined the, outer facevof the' 1 rack '32 is provided, with Ta series of notches -38- in spaced relation vertically correspond ng tothe spacing of the type of corresponding to thedistance between the stop 29and platen sections 1l. so that when the carrier ''2l is inserted through the guide passage 27 with its 7 r 38 to for adjustingthe carrier 720 lengthwise one type-platespace at a time and for this purpose the up-,

' 'Thelefthand bracket *25 is providedwith a vertical slot 25- for receiving the loweredge of thelofiset portion 20" of the plate 20 and assisting in holding said plate against lateral movement, the lower wall of the slot -25"- being adapted to be engaged-by the lower edge of the offset 20- for limiting the downward move mentof the plateg-20. j This type plate -20' is normally in its extreme downward position so that its uppermost'type plate 22 will b'e'registered with the platen sections '11-. but is adaptedto be moved upwardly one type plate space at a time when desired for successively registering the remaining type plates 22 with the platen section 11-, this upward movement being accomplished 9G by the forward and downward movement of the hand lever 37 and corresponding" rotation of the'gear 35 and resultant movement of the tooth rack ''32 upon which the plate 20 is mounted.

During this step by step'upward movement ofthe type plate 20fl the pawl 39 will? successively engage the notches V produce a clicking sound and to frictionally hold the plate init's adjustedhpo- 10 sition, it being understood that the notches 38 are spaced to the corresponding positions of the typeplates +22%. "j

Suitable means is provided' for limiting the upward movement of the type plate 205 .by the rotation of-the shaft 36- and for this purpose the hub as 37 of the hand lever -37 isprovided with a shoulder 4c2" adapted to engage a detent which 'is movable endwiseinthe outer end walls of the Mosh -84's:- and is yielding- 1y held in the path of the shoulder +42- by spring nai s shownin'Figures 1 and2.

,The locking member -44v is Preferably formed integral with the shaft-36 and consists of a segment'of'said shaft in that the portion'thereof entering the slot l5 is cutaway at -4aso that its diametrical thickness will be slightly less than the open upper end of the slot l5 while the lower portion of the slotnis of substantially the same radius as that of the locking member 44 z i w v as previously stated the keeper 6 mounted on the base 1- while the shaft 36,'having the locking member 4A is carried by the lid '2. The locking memthat'when the lever 37+ is adjustedto bring any one of the type plates -22- into registration with the platen sections 11' thewider part of the locking member 4 l will be'across the narrower part of the slot 4:5 to prevent, opening of the 'lid' but as 43 to limit further movement of the hand lever 37- and thereby to indicate to the operator that the lid is free to open; 1

In Figure3 the four positions of the hand lever 37 are shown by dotted lines for shifting the type plate to a corresponding number of positions for successively registering the type plates .22 with the platen sections 11c. as previously explained during which movements the locking 7 member '44 will remain in interlocking engagement with the keeper 6- tohold the lid closed, but when the lever 37 is moved to en gage its shoulder 42 with the detent 43 thelocking member -+4l will then I vassume a position in the slot 45 to per- $9 mit the lid to be opened.

The punching operation of the plunger -4:7- is preferably controlled by one of the platen jaws as 7 and for this purpose said plunger normally extends rearward-1y beyond the block 3& and is adapted to be engaged by a roller i7" on the upper rear edge of the jaw 7- so that at each forward movement of the j aw 7 to its printing position a corresponding movement will be transmitted by said roller 47 to the plunger 47 for effecting the cutting of the adjacent portions of the cards aand a-, the roller -47 being shown by full lines in Figure 8 and by dotted lines in Figures 5 ,and9.

The rear endof the plunger 4c7. isprovided with an upwardly extending radial pin 4 8 having its upper end adapted tointermittingly and automatically operate a feeding mechanism for the inking ribbon at each outward movement of the plunger in a manner hereinafter more fully described.

This punch and die 51 are located ad'- j acent the lefthand edges of the cards so that when the cards are punched the remaining portions thereof will be free to move down wardly at the inside of the punch and die as requiredvfor eifecting successive removals of portions of the adjacent edges of the cards in orderto permit'successive impressions of the type of both of the carriers -20 and 21 to be made simultaneously on the cards in transverse alinement and in sequence from the bottom upwardly.

These type impressions are adapted to be made upon both sides of the cards from both 65 spindles 757- at "opposite sides ofthe plane ends thereof approximately one-half the 'lengthzof the cards from either end and in order thatthe inward movementof the cards "by hand may be automatically limited to ap' proirim ately halflthe length thereof, I "have provided a V-shaped"stop 53, Figure 9,'

A holding pawl 68 is mounted upon a relatively short post 69e-on the lid 2 for engaging the teeth ofthe ratchet wheel and holding the latter against reverse movement. This holding pawl 68-' lies closely adj acent the ratchet pawl65'- and when it is desired-to rewind the ribbon uponthe reel as56 both pawls -6$ and +-65 may be simultaneously tripped from engagement with the ratchet whcel ti by means of a rock shaft 70 which is journaled in the lid 2 and is provided with a hand Wheel orknob 71 by which it maybe operated, said rock shaft being provided with a radially projecting pin --Z2- io-rengag ng and tripping the pawls as shown more clearly in Figure 6.

Thisntripping 'otthe pawls to permit'the irewin ding ofthe ribbon upon the reel -56 is best efiected when the lid, is in its closed position and the platent jaws brought to their printing:positions at which time-the roller Y4:7" will have moved the plunger l7-r inwardly thereby operating the lever +766 towithdrawv-th'e pawl -65 out of g g teeth of the ratchet wheel 64-}; A 3 l lVhen the ratchet wheel is released the reel +56? may be. operated by hanl through the medium of a hand wheel which extends through an opening in i3l1811d- 2 518 7 shown more clearly inFigurel.

In order thatthe cards and amaybe properly alined with the printing mechanism wheninserted in-themachine the lefthand edges of said cards are yielding-1y held against the correspondingguide mem bers 25' by yieldingabutinents l iadaptedtoeng age the righthand edges of the cards as shown more clearly in Figures 5 a and 6, each abutment being provided with an outwardly projecting stem 75', guided 1n stop openings in a-housing'76 which is secured to the undersideofi the -lid%2 springs 'Z7, surrounding their respective stems shown more clearly in Figure. 6. The guide v open ng for the plunger 47. is open at. its viipnt end t o-permit the dischargeof the punched out portion of the cards into a suitable receptacle which is mounted within the base -1 directly under the front end of the guide, opening as shown mor clearly in Figures 8, 9 and 10, said receptacle being removable to permit the waste to be dumped when desired.

Operation The operation briefly described is as follows v ti've positions after which the type carriers 20 and 2l will be placed in operative position within their respective guides, the

carrier 20 being in its extreme down position thereby" rocking the hand lever 37 to its extreme rearward position shown in Figure 1.

This latter operation brings the uppermost typeplate -22 into registration with the platens l1- while the type plates 23 on the carrier 2l will be registered with the platen sections l1.

The cards '-a and a are then inserted into the machine as illustrated in Figures 10 and 11 until limited by'the engagement of their-lower ends with the abutment '4-6 whereupon the hand lever 19 will be drawn forwardly and downwardly :tor bringing the platen jaws into printing co-action with said type plates for impressing the registering rows of type upon v said cards near the lower edges thereof and at the same time the forward movement of the jaw -7 will cause its roller -47 to engage and operate the plunger 47 for cutting away portions of the lower lefthand edges of the cards and permitting said cards to be advanced by hand into the machine a distance corresponding to the cut away por tions ready for another printing operation in a line directly above that'previously made.

These printing and cutting operations may be repeated as often as desired until practically one-half of the length of the card is printed after which the cards may be reversed end for end and the printing and cutting operations repeated on the remaining halves of the cards it being understood that each printing'operation impresses the iden V tificationcharacters and dates in ahnement upon corresponding portions of both cards.

it a card for a different borrower having a different identification character is to be used with the same dating characters the cardsi'or that particular borrower will be inserted in the machine and the printing and cutting operation repeated in the manner described. v

This first dating impression made upon the cards maybethe date of issue or the date of return of the article to or from the borrower. a

" It willcbe noted upon reference to Figure? 7 that the four type plates 22?- on the car.- rier 20 bear different dates in sequence may represent the dates uponwhich the'borrowed articles are to, be returned it being from the top downwardly and in this instance understood that different books'or other articles will be ods.

It therefore loanedfor different time peri follows that ifthe date of return of one borrowed articleis diflerent from another the carrier 20* will have to be shifted by drawing the hand leverv *3?- forwardlyfto bring the] proper type plate 22 into printing position after which the printing and punchingoperationipreviously described will be repeated.

When the use of the type plates 22 7 5' the carrier have been exhausted. the

carrier may be removed by simply pressing the pawl 43] inwardly and then rocking I the lever 37,l downwardly. until its;-shoul-' der +42i engagesthe pawlwhere- 'upon 'the lid r 2 beraised. and the carrier -'20 withdrawn from the'lid. H

7 When the carrier- 20 is withdrawn in the manner justj describedthe plates 22' may be removed from the bottom downwardly and replaced by other platesafter which the carrier +20+- with the other plates there in may be replaced withinthemachine by i simply pressing the same downwardly which will automatically return the lever +37 9 to its starting position, itbeing understood that when the lid is closed and the lever 3'? restored to its first position the lock- "ing member -44 will be adjusted in its keeper 6 to lock the lid against opening movement. V I V V The carrier 21 for the type plate 23-+"is preferablymade offcardboard of "about the same-size and form as the cards I 'a-" and a"' and-1s retained in the public library: for identification of a particular borrower to be used in the machine for impressing u'ponthe cards 'a and V-'ct "the identification character'of that particular borrower ,opposite the date of issue orireturn of the borrowed article.

That isythe public librarycarries in stock a'considerable number of different identifiration type plates 23 so that one may be issued foreachborrower to be retained in the library aft-erea chfluse.

Ittherefore follows that if the type plates '-23"are' made removable from the carrier; v -21 different type plates may be used with the same carrier while on theother hand if thetype plates are fastened permanentlyto the carrier a corresponding number o-fcarriers' 'will have to'be issued and retained-in.
